Abstract

The present invention provides a method for automatically setting an initial position of a massage chair by sensing a neck or shoulder position and a massage chair to which such a method is applied.

Description

A method of setting a massage chair initial position according to a neck or shoulder position and a massage chair using the massage chair according to the position of the neck or shoulders,

The present invention relates to a method for automatically setting an initial position of a massage chair by sensing a neck or shoulder position and a massage chair to which such a method is applied.

Since the massage chair provides a customized massage while fixing the user to a certain degree using various air bags and then introducing or discharging the air into the air bag or moving a separate massage ball, in order to maximize the massage feeling, It is important to measure the body shape of the user and set the initial position of the massage chair accordingly.

First, the massage ball mounted in the backrest 10 is positioned in the center of the back of the user. Second, the length of the massage ball So that the leg 20 can be set according to the leg length of the user.

For this purpose, two methods of setting the initial position of the backrest 20 according to the position sensing of the upper body and the initial position sensing of the leg 10 according to the position sensing of the lower body have been performed in parallel.

In the case of the upper half of the body, a separate massage ball provided in the backrest 10 is ascertained while moving up and down.

In detail, a massage ball capable of moving up and down is mounted inside the backrest 10. A sensor is provided at a portion connecting the massage ball to the massage chair frame, and the sensor senses the pressure applied to the massage ball can do. Accordingly, when the user is seated in the massage chair, the massage ball moves up and down from the inside of the backrest portion 10 in order to set the initial position before performing the massage. While the pressure is continuously sensed while moving from the bottom to the top, If the massage ball is lowered, it is judged that the massage ball has passed through the shoulder (the backrest portion and the user's body are not in contact with each other) and reached the neck portion, and the position is set to the shoulder position.

In the case of the lower half body, a method using a sensor of the leg portion 20 is generally used.

In detail, a sensor is provided on the foot part of the foot 20 where the user's foot is touched, so that the pressure applied thereto can be sensed. Accordingly, before the user sits on the massage chair and performs massage, the leg portion 20 is initially extended to the maximum length for initial position setting, so that the foot portion is distant but is gradually elevated to sense the pressure, When the predetermined threshold value is exceeded, the position of the foot plate becomes the initial position at that time.

Such a method has the following problems.

First, there may be a problem with the accuracy when using the sensor provided in the massage ball.

In recent years, there have been many cases in which a heating member for providing a warm feeling together with a back massage is attached to a massage ball in many cases. When a sensor provided on the massage ball is used, the massage ball is vulnerable to heating due to a heating member and may malfunction.

Second, both of the back part 10 and the leg part 20 should be equipped with sensors.

If any one of the sensors fails, the initial position is not set properly.

In addition, since the length of the upper half of the body and the length of the lower half of the human body are related to each other to some extent, even if only one of them is measured, data to be further measured can be reduced. And the manufacturing cost is increased.

Third, the initial position should be newly set for every user.

In the case of a massage chair, which is mainly used in the home, since the user is limited, it is possible to reduce the time or power for setting the initial position if the user continuously uses the initial position after setting the initial position. However, Function is not implemented.

Figure 2 schematically shows a system for carrying out the method according to the invention.
Figure 3 shows a flow chart for explaining the method according to the invention.

In the present invention, "neck position" means the lowest position of the neck.

In the present invention, the "shoulder position" means the uppermost position of the shoulder.

Therefore, the neck of the person is connected to the shoulder, and the neck position and the shoulder position are substantially the same position, so that the distance from the predetermined reference point to the neck position and the distance from the predetermined reference point to the shoulder position are substantially the same, Is referred to as a portion of the waist or pelvis, the distance is referred to as the "upper half length ". Herein, the predetermined reference point is defined as the intersection of the massage chair back portion and the seating portion for convenience of calculation and sensing in the present invention.

In the present invention, the term "initial position" means a shape in which a massage chair is set before analyzing a user's body shape to perform full-scale operation (i.e., massage operation). In particular, the concept includes not only the position of the massage ball in the backrest according to the upper half body shape but also the length of the leg portion.

Description of massage chair

A massage chair will be described with reference to Figs. 1 and 2. Fig. Description of the members similar to the conventional massage chair is omitted.

The massage chair according to the present invention is connected to the backrest part 10 and the backrest part 10 to which the user is seated when the user is seated, a seating part where the hips and the thighs are contacted when the user is seated, And a leg portion 20 having a groove and on which a leg of a user can be placed.

A massage ball is mounted on the backrest 10.

The massage ball may be interlocked with a heating member for providing a thermal feeling.

The massage ball can move up and down in the backrest 10 by the massage ball position moving actuator 31.

In one embodiment of the present invention, the sensor assembly S may be provided in a massage ball or an assembly thereof.

As a result, the body shape can be analyzed by sensing the neck or shoulder position of the user while moving the massage ball up and down.

In another embodiment of the present invention, the sensor assembly S may be mounted within the backrest 10 independently of the massage ball.

In this case, a plurality of sensors are vertically and vertically positioned in the sensor assembly S, and the shoulder position can be sensed by sensing the uppermost position of the plurality of sensors which the object touches. Alternatively, The neck position can be sensed by sensing the position of the neck.

When the user is seated in a massage chair, the shoulders touch but the neck does not touch.

On the other hand, on the lower end of the leg portion 20, a footrest portion to which the sole comes in contact when the user is seated is provided.

The foot part can be moved up and down by the leg actuator 32 so that the foot part moves to the lower side for the legged user and moves to the upper side for the user with the shorter leg so that it can be matched to the calf length of the user.

The input module 100 is a kind of touch panel through which a user applies an electrical signal for operation.

The input module 100 is interlocked with the database 105 in which the user identification signal and the corresponding initial position setting value are stored.

The neck or shoulder position sensing module 110 may sense the neck or shoulder position based on the sensed position from the sensor assembly S embedded in the massage ball or inside the backrest 10. [

The initial position calculation module 120 can check the length of the upper half body by comparing the sensed neck or shoulder position with the predetermined reference point on the neck or shoulder position sensing module 110. [

In order to calculate the length of the upper half of the user, the predetermined reference point is preferably an intersection point between the backrest 20 and the seating part. For example, if a reference point such as the bottom end of the backrest 20 is set It is acceptable.

Meanwhile, the initial position calculation module 120 is interlocked with the database 125, and the database 125 stores the length of the upper half body statistically confirmed and the length of the lower half body in advance.

For example, according to statistical data, the lower half of a person with an upper half of 429 mm is 848 mm, and data of a lower half of the upper half of the upper half are mapped and stored in the database 125, You can check the length of your lower body as you check it out.

In another embodiment of the present invention, the length of the lower body may be replaced by the length of the calf. This is because the leg portion 20 corresponds to the length of the calf. In this case, the length of the calf is mapped to the length of the upper half of the body and stored in the database 125.

The actuator driving module 130 drives the massage ball position shifting actuator 31 and / or the leg actuator 32 to set the massage chair to the initial position according to the lengths of the confirmed upper and lower half bodies.

Explanation of how to set initial position

Hereinafter, an initial position setting method will be described with reference to FIG.

First, the user attempts to start operation in the input module 100, and an "initial position setting signal"

The input module 100 asks the user for a user identification signal (S200). That is, it is checked whether or not the initial position is set in the massage chair.

If there is a user identification signal, the initial position set value mapped to the user identification signal is confirmed in the database 105. The initial position setting value includes information on the position on the backrest portion 20 of the massage ball and the length of the leg portion 10. Accordingly, the actuator driving module 130 sets a massage chair as an initial position setting value (S250).

If there is no user identification signal, the user body type must be analyzed for initial positioning.

Now, the neck or shoulder position sensing module 110 senses the neck or shoulder position of the user by the sensor assembly S provided in the massage chair (S300).

The sensor assembly S provided in the massage ball may be used as in the prior art. That is, when the massage ball moves up and down on the backrest 20 and the pressure sensed by the sensor assembly S changes by more than a preset range, the position is sensed to the neck or shoulder position.

In another embodiment, the sensor assembly S is provided on the backrest 10 and includes a plurality of sensors, which sense the position of the shoulder by sensing the uppermost position of the plurality of sensors that the object touches, The neck position can be sensed by sensing the lowermost position of the sensor where the object does not touch.

Next, the initial position calculation module 120 checks the length of the upper half of the body according to a predetermined method using the neck or shoulder position sensed in step S300, and confirms the length of the lower half body corresponding to the confirmed upper half body length (S400).

In the case of the upper half of the body, the initial position calculation module 120 confirms the distance between the neck or shoulder position sensed by the sensor assembly S and a preset reference point as the length of the upper half of the body. Here, the predetermined reference point may be an intersection point between the backrest 20 and the seating portion, but it may be any other point indicating the length of the upper half of the body.

In the case of the lower half of the body, the initial position calculation module 120 can check the length of the lower half of the body, which is previously mapped and stored in the database 125 according to the length of the upper half of the body.

Next, the actuator driving module 130 drives the massage chair using the length of the upper half body and the length of the lower half body, which are confirmed in step S400, to set the initial position.

Specifically, the actuator driving module 130 operates the massage ball position shifting actuator 31 corresponding to the length of the identified upper half of the body, so that the massage ball can be positioned at a predetermined position on the back portion 20. That is, the massage ball is located at a half or two-third of the upper half of the body so that the massage ball is located at the center of the user's seat. For example, when the length of the upper half of the body is 450 mm, the massage ball may be located 300 mm from the lowermost end of the backrest 20.

In addition, the actuator driving module 130 actuates the leg actuators 32 according to the average length of the lower half of the body to adjust the length of the leg portions 10. For example, the footrest can be raised or lowered appropriately.

In another embodiment of the present invention, the actuator drive module 130 may further adjust the headrest provided above the backrest 20, corresponding to the identified length of the upper half of the body. That is, if the length of the upper half of the body is long, the head restraint may be raised, and in the opposite case, the head restraint may be lowered to appropriately reach the head position of the average user.

In another embodiment of the present invention, the length of the lower half of the lower body calculated in step S400 may be the length of the calf.

That is, in this embodiment, the length of the calf according to the length of the upper half of the body is previously stored in the database 125, and thus the initial position calculating module 120 calculates the length of the calf previously stored according to the confirmed upper body length Thereby confirming the length of the lower half of the body, and the actuator driving module 130 operates the leg actuator 32 accordingly.

While the present invention has been described with reference to exemplary embodiments thereof, it will be understood by those of ordinary skill in the art that various changes in form and details may be made therein without departing from the spirit and scope of the present invention as defined by the following claims.
